I have a Shopsmith (with the small table) that I bought directly from Shopsmith about 45 years ago. So, I guess it's the Mark V model 500? I have been hearing a clicking / ticking / rubbing sound from the drive belt end of the headstock for quite a while, so I did a little research and discovered that it is most likely caused by a worn sheave spacer behind the fan sheave. I dismantled the sheave assembly only to discover that there isn't a sheave spacer.
Did Shopsmith not put a spacer in this year Mark V, or do you guys think it was just mistakenly left out during assembly? I did have quite a bit of struggle to remove the sheave in that the set screw was set so tightly that it bent the end of key.
I've ordered a replacement sheave spacer (#504205) from Shopsmith.
